A frog sitting on the handle of a saucepan on a hot stove. The frog in this photo was unharmed. [1] The boiling frog is an apologue describing a frog being slowly boiled alive. The premise is that if a frog is put suddenly into boiling water, it will jump out, but if the frog is put in tepid water which is then brought to a boil slowly, it will ...
Water-holding frogs are ectothermic, [8] meaning they depend on external sources of body heat. Aestivation is a behaviour characteristic of water holding frogs. It is similar to how other animals hibernate, except it takes place during summer as opposed to winter when weather conditions are hot and dry. This behaviour is a response to high ...
The common frog is a poikilotherm and is able to function over a wide range of body core temperatures.. A poikilotherm (/ ˈ p ɔɪ k ə l ə ˌ θ ɜːr m, p ɔɪ ˈ k ɪ l ə ˌ θ ɜːr m /) is an animal (Greek poikilos – 'various', 'spotted', and therme – 'heat') whose internal temperature varies considerably.
In captivity, C. cranwelli and C. ornata are the most popular species, [4] along with the "fantasy frog", a captive-produced hybrid between C. cranwelli and C. cornuta. These frogs can live in a terrarium with a floor area 8-10 times the size of the frog. [4] They commonly cover themselves with substrate or just sit contentedly in the water.
Folklorist Andrew Lang listed myths about a frog or toad that swallows or blocks the flow of waters occurring in many world mythologies. [1]On the other hand, researcher Anna Engelking drew attention to the fact that studies on Indo-European mythology and its language see "a link between frogs and the underworld, and – by extension – sickness and death".
David Blaine reportedly swallowed a frog during a performance at a recent Google retreat.
However, endothermic homeotherms (generally referred to as "warm-blooded" animals) not only produce more heat but also possess superior means of retaining and regulating it compared to other animals. They exhibit a higher basal metabolic rate and can further increase their metabolic rate during strenuous activity.
Such organisms (frogs, for example) rely on environmental heat sources, [3] which permit them to operate at very economical metabolic rates. [4] Some of these animals live in environments where temperatures are practically constant, as is typical of regions of the abyssal ocean and hence can be regarded as homeothermic ectotherms.
